A Remarkably well-preserved fossil unearthed in Morocco is forcing palaeontologists to re-evaluate the evolutionary origins of ankylosaurs, a group of armoured dinosaurs. The new species, named Spicomellus afer, roamed North Africa approximately 165 million years ago during the Jurassic period.
Extravagant Armor Challenges Existing Theories
The Spicomellus afer fossil, discovered near Boulemane, Morocco, presents an unexpectedly elaborate array of bony armour. Experts describe the creature as appearing “tank-like,” covered in spikes and featuring a massive, disproportionately large armoured collar around its neck. This discovery is especially significant as it represents the oldest known ankylosaur specimen to date.
“It’s absolutely bristling with spikes all over its body,” Explains Professor richard Butler,of the University of Birmingham,and a co-leader of the research team. “It has these incredibly distinctive spikes around the neck – an armoured collar that is absolutely enormous and totally out of proportion to the rest of the body, smaller spikes projecting out of the ribs, and at the end of its tail it would have had some kind of weapon.”
A Closer Look at Spicomellus afer
reconstructing the dinosaur’s anatomy proved challenging due to the incomplete nature of the fossil remains. Scientists meticulously assembled the scattered armour pieces to determine their original placement. Preliminary analysis indicates that Spicomellus afer measured around 4 meters in length and weighed approximately two tonnes. The fossil also suggests the dinosaur possessed a club-like structure at the end of its tail, a feature previously believed to have evolved much later.
| Feature | Description |
|---|---|
| Species Name | Spicomellus afer |
| Age | approximately 165 million years old (Jurassic Period) |
| Location of Discovery | Boulemane, Morocco |
| Estimated Length | Around 4 meters |
| Estimated Weight | Approximately 2 tonnes |
Did You Know? Ankylosaurs were herbivores that roamed the Earth for nearly 100 million years, surviving until the Cretaceous-Paleogene extinction event.
beyond Defense: A Display of Dominance?
While the armour of later ankylosaurs is widely understood as a defensive adaptation, the sheer extravagance of Spicomellus afer‘s spikes suggests a different purpose. Researchers believe the spikes may have been used for displays of dominance or attracting mates. “when you see the neck collar of this thing,it seems like total overkill,” notes Professor Butler. “It does seem like the kind of thing that would’ve complicated its life.”
Fossil Poaching Threatens Scientific Progress
The discovery of Spicomellus afer is tempered by concerns over illegal fossil hunting in Morocco. While the primary fossil is housed at the Dhar El Mahraz Faculty of Sciences in Fez,fragments believed to belong to the same specimen have surfaced on the black market,reportedly offered for sale at prices up to £10,000. “There’s a huge problem with fossil poaching in Morocco,” said Butler. “Bits of this specimen have been for sale in the market in Europe and North America.”
The Evolution of Ankylosaurs: A Timeline
The discovery of Spicomellus afer pushes back the timeline for the growth of key ankylosaur features, such as tail weaponry, by approximately 30 million years. This highlights the importance of ongoing palaeontological research in refining our understanding of dinosaur evolution. The fossil record remains incomplete, and each new discovery has the potential to reshape our perceptions of prehistoric life.
pro Tip: Support ethical palaeontology by advocating for strong regulations that protect fossil sites and discourage the illegal trade in fossils.
Frequently Asked Questions about Spicomellus afer
- What is Spicomellus afer? Spicomellus afer is the oldest known ankylosaur species, discovered in Morocco and dating back 165 million years.
- What makes Spicomellus afer unique? Its extraordinary and elaborate armour, particularly the large neck collar and abundance of spikes, sets it apart from other known ankylosaurs.
- How does this discovery impact our understanding of ankylosaur evolution? It suggests that key ankylosaur features, like tail weaponry, evolved earlier than previously thought.
- What is being done to address fossil poaching in Morocco? Efforts are underway to strengthen regulations and combat the illegal trade in fossils, but more action is needed.
- What was the likely purpose of the elaborate armour on Spicomellus afer? While some armour served as defence, the excessive spikes likely served a display function for dominance or mating purposes.

Oldest Known Ankylosaur Fossil Discovered in Morocco: Insights into Spiked Dinosaurs
Unearthing a Prehistoric Giant: The Moroccan Ankylosaur
A groundbreaking paleontological finding in Morocco has revealed the oldest known ankylosaur fossil, dating back over 100 million years to the Cretaceous period. This find significantly expands our understanding of ankylosaur evolution and distribution, especially within Africa – a region historically underrepresented in ankylosaur fossil records. The newly discovered species offers crucial insights into the early progress of the distinctive armor and weaponry characteristic of these “armored dinosaurs.”
Key Features of the newly Discovered Ankylosaur
The fossil, meticulously excavated from Moroccan sedimentary rock, exhibits several key features that distinguish it and provide clues about its lifestyle:
Early Armor Development: The fossil displays evidence of developing osteoderms – bony plates embedded in the skin – suggesting this individual was in the process of acquiring the full armored protection seen in later ankylosaur species.
Spiked Tail (Thagomizer): While not fully developed,preliminary analysis indicates the presence of nascent spikes at the end of the tail,a feature known as a thagomizer,used for defense against predators.
Skeletal Structure: The preserved skeletal remains reveal a robust build, typical of ankylosaurs, indicating a quadrupedal stance and a herbivorous diet.
Dental Morphology: Analysis of the teeth suggests the dinosaur was adapted for shearing tough vegetation, consistent with other known ankylosaur feeding habits.
Morocco’s Rising Prominence in Paleontology
This discovery highlights Morocco as an increasingly critically important location for paleontological research. The Sahara Desert, once a lush environment during the Cretaceous period, is proving to be a treasure trove of prehistoric life.
Geological Meaning: The geological formations in Morocco preserve fossils from a critical period in dinosaur evolution, offering a unique window into the past.
Previous Discoveries: Prior to this, Morocco has yielded significant finds including Spinosaurus remains, demonstrating a diverse prehistoric ecosystem.
* Expanding Research: Increased investment in paleontological expeditions in Morocco is expected to yield further discoveries, perhaps reshaping our understanding of dinosaur evolution.
Ankylosaur Evolution: A Continental Puzzle
The Moroccan ankylosaur fossil adds a crucial piece to the puzzle of ankylosaur evolution and biogeography. Previously, the majority of early ankylosaur fossils were found in North America and Asia. This African discovery suggests:
- Wider Geographical Distribution: Ankylosaurs were more widely distributed across the globe during the Cretaceous period than previously thought.
- Continental Connections: The find supports theories about land bridges and continental connections facilitating dinosaur migration between Africa, Europe, and Asia.
- Self-reliant Evolution: It raises the
